Very interesting video, thank you for posting this.

Valve fluid transfer system is a pipeline control unit, which is used to change the channel section and flow direction of medium, with the diversion, close, regulating, throttling, just back, diversion or overflow relief functions. For fluid control valves, valve from the simplest to the most complex automatic control system used in a variety of Globe Valve, its many varieties and specifications, the valve nominal diameter from large to tiny instrument valve Path up to 10m of industrial pipeline valves. Valve can be used to control water, steam, oil, gas, slurry, corrosive medium, the liquid metal and radioactive fluids and other types of fluid flow, working pressure valve to 1000MPa from 0.0013MPa the high pressure, Working temperature from -269 ℃ to 1430 ℃ ultra-low temperatures. Control valves can use a variety of transmission modes such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic - hydraulic, electro - hydraulic, gas - hydraulic, spur gears, bevel gear drive etc.; can be pressure, temperature or other forms of sensor signals under, according to the requirements of scheduled actions, or do not rely on sensor signals and a simple open or closed, the valve body to rely on drivers or auto parts for lifting hoist , sliding, rotating pendulum, or rotary movement, thus changing the size of its flow area to achieve its control function.
